Well, i wouldnt write here if it worked for me, im running win 10.the game runs perfect before i try to activate the trainer...Perhaps it has something to do with the trainer being built for Pre-Release and not for final release?

I will say as soon as you start the game and trainer at the same time it crashes the game. Otherwise the trainer works perfectly with the retail release. The code hasn't changed much other than the actual story related items/rewards that were downloaded into the game.

Agreed with everything noted here. Also running Win 10. Ran into the non-loading black screen issue when activating the trainer at main menu. However, loading game and save first and then activating trainer works like a charm. Went from early release version to release version today and everything still works fine, as long as you activate trainer after loading into game.
